His first appearance was in Batman #705, where When members of a secret order turn up dead and tortured in Gotham City's Chinatown district, I-Ching informs Batman that he fears an ancient mask called the Beholder is the target. And that the only one who might be capable of locating the mask, a young boy named Luki Lo is now held captive of The Sensei. Batman connects this case to that of a missing satellite architect. With few clues to go by and the stakes getting higher, Batman races to locate the surviving members of the order before it's too late. Yet, they didn't save him, but Batman leaves instantly for Gotham.

In Batman #706, Elsewhere, I-Ching leaves a healing Peacock to go after Sensei and save her brother. One of the shops in the streets below is a butcher shop, where I-Ching had already busted the door in. Inside, Dick finds I-Ching’s glasses, and before he knows it, is ambushed by Sensei.

In Batman #707, Batman arrives out of nowhere and warns Sensei that the power is too strong, but Sensei believes himself to be worthy to wield the power and disregards the warning. Suddenly, the mask comes off and Luki grabs it and I-Ching declares him the rightful owner. Enraged, Sensei attacks Luki and strikes the mask, breaking it into pieces. Knowing that he has lost this battle, Sensei saves face by picking up the pieces of the mask and escaping. In the aftermath, Peacock and Luki entrust Batman with the piece of the mask that Sensei was not able to salvage, warning him that there is no doubt he will one day return to have it for himself.
